I always book through my host for our rooms, but I use the snail mailers for the cash slot dollars. Take the mailer, they scan it and say I'm all set. Anyway, I never received the Sept/Oct mailer even though the offers are in my on-line account. So I called and ended up getting connected to the Player's Club and they told me you don't need the mailer as long as you have ID, the offer can be loaded onto my card. I thought about this for a day and didn't feel comfortable with that answer, so I called back and asked for casino marketing. Essentially, I got the same answer except she said it is automatically loaded on the card when you check in and if it isn't, check with Player's Club. She also said it's easier to just bring the mailer. Well duh, if I got one, I would bring it. We'll see how this works in Oct because our ritual is to get into the room, unpack and head to the Player's Desk to get our credits. I've never gone directly to a VP machine, so I don't know if the credits were already on the card after check in. I'm skeptical.
